The underground construction ventilation fan is tailored for use in early-stage tunnel boring, shaft sinking, and drift construction, where rapid air exchange is critical for worker safety.
These portable fans feature axial impellers and flexible duct attachments, delivering 2,000–20,000 CFM at moderate pressures. Reinforced housings and splash-proof motors withstand wet and dusty conditions.
Variable frequency drives (VFDs) provide adjustable airflow, matching ventilation to excavation rates and reducing noise and energy consumption during pauses in work.
Quick-release duct clamps, integrated handles, and skid frames enable rapid deployment and repositioning, making these fans indispensable for safe, efficient underground construction.
